Cov hluav taws xob hluav taws xob loj teeb tsa kev sib tw teeb tsa, induction rauv Cov khoom lag luam inductive xav tau reactive zog nrog rau kev ua haujlwm lub zog. Lub zog reactive yog ntsuas hauv kilo volt-amperes-reactive-reactive, thiab ua haujlwm zog yog ntsuas hauv kilowatts. Cov neeg siv lub zog ua haujlwm los ua haujlwm tiag tiag. Txawm li cas los xij, cov hluav taws xob reactive yog qhov tseem ceeb rau kev txhawb nqa daim teb sib nqus los ntawm kev thauj khoom hauv inductive. Thaum ob lub powers tau sib xyaw ua ke, ces lawv tsim lub zog pom tseeb. Lub zog hluav taws xob pom tseeb yog ntsuas hauv KVA, uas yog lub npe hu ua Kilovolt-amperes.
Lub zog yog dab tsi?
Lub zog siv hluav taws xob yog qhov ntsuas ntawm kev ua tau zoo. Nrog nws cov kev pab, cov khoom hluav taws xob tau hloov mus rau hauv lub zog hluav taws xob ua haujlwm tseem ceeb. PFC kuj tseem hu ua qhov piv ntawm kev ua haujlwm lub zog rau lub zog pom zoo. Lub PFC siab yog qhov ntsuas uas pom cov hluav taws xob siv hluav taws xob yog siv lub zog kom zoo. Txawm li cas los xij, qhov qis PFC qhia tau hais tias lub zog tsis tu ncua thiab txo cov hluav taws xob muaj peev xwm. Qhov laj thawj tom qab qis PFC tuaj yeem yog qhov sib txawv thiab qhov hloov ntawm lub terminals ntawm cov hluav taws xob.
Qhov Zoo Ntawm Kev Siv Pfc Kev Paub Kev Kho Mob Capacitors
Txhawm rau nres lub zog hluav taws xob, ob peb lub tuam txhab hluav taws xob muab lawv cov neeg siv khoom nrog PFC uas nyob hauv qab tus nqi tshwj xeeb. Nws muab kev txhawb siab rau cov neeg siv khoom nrog txoj cai pf uas yog 0. 95. Nws reassures cov neeg muas zaub los txhim kho lub zog kev txhim kho capection capinitors hauv lawv cov txheej txheem hluav taws xob.
Thaum nws los txog rau qhov zoo, ces muaj ob peb qhov zoo ntxiv rau lub zog ua kom haum correctors capinitors. Qee tus ntawm lawv tau teev tseg hauv qab no:
• Txhim kho cov hluav taws xob
• Maximize lub peev xwm ntawm lub system
• Txo cov poob
• Txo cov nqi hluav taws xob tsawg
Ua ntej xaiv cov capacitors rau pfc kho, thauj tas li lub nra, thauj khoom muaj peev xwm thauj khoom, ntaus nqi, thiab cov txheej txheem ntawm kev thauj khoom pib.
PFC Kev Kho Mob Capacitors ua haujlwm li cas?
Nws yog ib qho tseem ceeb uas yuav tau nruab lub zog kev txhim kho capinitors raws li cov txhab nyiaj ntawm lub peev xwm capacitors thaum cov chaw lossis hloov chaw ntau. Nyob rau hauv qhov teeb meem ntawm linear loads, nws yooj yim los txhim kho lawv raws li tus kheej capincitors. Nws tsis yog qhov nyuaj los hloov cov capacitors thaum lawv tsis tas yuav tsum hloov pauv txawv. Txawm li cas los xij, lub txhab nyiaj teeb tsa ntawm cov capacitics muaj tus nqi tsawg rau ib kvar. Nws tseem muab qhov tseeb ntawm PFC kev kho kom muaj peev xwm thaum siv lub tshuab tsis siv neeg hloov.
Kev ua raws li qhov yuav tsum tau ua ntawm cov chaw tshwj xeeb, nws yog qhov ua tau rau nruab ib qho tsau lossis kho tshuab hloov mus kuaj teeb tsa. Cov txhab nyiaj taag pfc tsis ruaj khov tuaj yeem hloov mus thaum lub zog hluav taws xob yog rau, tawm thaum cov thauj khoom tau tawm. Cov capacitors tau dag zog thaum lub PFC kho tau yuav tsum muaj. Nyob rau hauv ntau cov chaw thau khoom, qhov kho PFC thiab cov khoom siv hluav taws xob uas yuav tsum tau hloov pauv ntau zaus. Lub tshuab automatic capacch systems yog qhov zoo tagnrho rau cov chaw no. Lawv tuaj yeem tswj tau yooj yim rau kev txhim kho thiab kho dua tshiab.
Cov khoom siv hluav taws xob loj xws li cov motors loj, roj hluav taws xob, roj kev sib tsoo, thiab cua tshuab muaj cov cuab yeej sib tsoo. Rau cov no cov khoom siv loj loj, nws yog qhov tsim nyog los ua kev siv lub tshuab tsis siv neeg captic system. Hauv qhov no, cov tsev txhab hluav taws xob hluav taws xob dawb hluav taws xob yuav ua haujlwm zoo.
